Application filed August 3, 1914. Serial No. 856,309.

To all whom it may concern.

Be it known that we, WALLACE P. AN- oELo, A HEATH ANGELO, and FRANCIs B. RUssI, citizens of the United States, and residents the said WALLACE P. ANGELO and A HEATH ANGELO of the city and county of Alameda, and the said FRANCIS B. Rossr of the city and county of San Francisco, and State of California, have invented a new and useful Improvement in Shipping-Containers, of which the following is a specification.

Our invention relates to shipping containers for perishable matter wherein an inner compartment is provided in which a cake of ice is insulated; and the objects of our invention are first, to provide a cheap shipping container adapted to preserve perishable matter; second, to provide a cheap shipping container adapted to contain a suitable cooling agent; third, to provide means for preserving the cooling agent; fourth, to provide meansfor preventing the moisture from the melting lce from coming into contact with the perlshable matter; fifth, to provide means for draining the moisture of the melting ice from the container; sixth, to provide a container of the character described that may be easily and cheaply constructed so that the said container may be destroyed or thrown away at the end of the journey and thus eliminate the expense of a return charge; and seventh, to provide means for re-icing the container. l/Ve accomplish these several features by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar'parts throughout the said specification and drawings and in which- Figure 1 is a broken sectional view of the container disclosing the outer and inner containers and the'space between, the false bottom, the door for re-icing, the manner in which the ice is insulated, and the slots for drainingvthe container. Fig. 2 is a horizontal sectional view taken on line XX on Fig. 1 of the drawings in the direction indicated by the arrow, one-half of the inner container being removed, and Fig. 3 is a broken view of the false bottom removed from the container.

We propose to provide a cheap shipping container made of a cheap material such as heavy parafiined card board or of a comparatively thin wood veneer, preferably, of the latter, having an inner cylindrical container of the same material, said inner container being adapted to contain a cake of ice or other similar cooling agent which is surrounded by a cheap granulated insulating material such as ground cork or, preferably, saw dust. The outer surface of the inner container is surrounded with a suitable cheap water proof material such as paraffined paper in order that the moisture of the melting ice will be prevented from coming into contact with the perishable matter being shipped.

The container is purposely made of a cheap construction and material so that it may be destroyed or thrown away after the con tents have been removed therefrom. In this manner the expense occasioned by the return shipment of an empty container is eliminated.

Referring to the drawings, the numeral 1 is used to designate an outer container of thin wood veneer, preferably cylindrical in form and secured in the usual manner by the suitable hoops 2. The container 1 is provided with the usual circular bottom 3 having suitable slots l at several points in the periphery thereof. The bottom 3 rests on the inner hoop 5 and is further secured in position by means of a second inner hoop 6 which also acts as a support for a false circular bottom 7, which is provided with a concentric central aperture 8 through which the inner drum 9 projects to the bottom 3. The inner hoop 6 also serves as a separator for the false bottom 7 and the bottom 3, the purpose of which will hereinafter be more fully described.

1 The inner drum 9 is set loosely on the bottom 3 so that any moisture or drippings from a cylindrical cake of ice 10 set within the inner container 9 may flow into the annular channel 12 between the false bottom 15, preferably saw dust, is introduced, so

that the ice 10 is completely surrounded by the insulating material 15. The circular cover 16 is secured within the upper end of the container 1 in the usual manner by an inner hoop 17 and rests upon the upper end of the inner container 9 so that the said inner container 9 is effectively retained between the bottom 3 and the cover 16. Thecover 16 is provided with a suitable door 18, which may be secured in any manner, so that access may be had to the inner container 9 for the purpose of re-icing without removing the said cover 16 or disturbing the contents of the container 1.

The perishable matter to be shipped in the container 1 is packed in theannular space 20, betweenthe inner cylindrical container 9 and the outer container 1. Instead of packing the ice around the perishable matter, so that the ice is exposed to the outer and warmer portion of the container, the ice or cooling agent 10 is packed within the inner container 9 and insulated from the atmosphere by the insulating material 15.

In this manner, the cold air radiating from the ice 10 is absorbed by the perishable matter in the annular space 20 before it reaches the exterior of the container 1, the perishable matter thus acting as a further means of preserving the cooling agent or ice 10. The paraffin paper 14 around the container 9 will prevent the moisture occasioned by the melting ice from reaching or coming in contact with the perishable matter in the an-' nular space 20.

WVhile the insulating material 15 is a nonconductor and preserves the ice 10, it will readily be observed that as the ice 10 melts the insulating material 15 absorbs and becomes saturated with cold water which will in turn act as a cooling agent and tend to preserve the perishable matter within the annular space 20. As the insulating material 15 becomes thoroughly saturated with the water from the ice 10, said water will accumulate at the bottom of the inner container 9 and will drain off into the annular space 12 between the false bottom 7 and the bottom 3 and through the slots 4: in the said bottom 3 and out of the container 1.

It is evident from the foregoing that we have provided a cheap, practical container for shipping perishable matter and one thatis also adapted to preserve the perishable matter by means of the cooling agent for a considerable length of time, and the con tainer being constructed of a cheap material may be constructed cheaply, so that the container may only be used once and destroyed or thrown away after the perishable matter has been removed therefrom, thus eliminating the expense of a return charge in ,shipping the container back to the point from which the perishable matter was shipped it is also obvious that the inner container 9 may be re-iced without disturbing or removing the contents from the container 1.

It is obvious that a cylindrical container possesses more stability by reason of its shape and may be more cheaply produced than a rectangular container which requires of similar materialhaving a concentric eircular aperture therein; means arranged to retain a space between the bottom and the false bottom; an inner cylindrical container composed of comparatively thin wood veneer projecting through the aperturein the false bottom and to the bottom of the outer container so as to provide an annular space above and below the false bottom; and a, suitable cover secured to the top of the outer container and arranged to retain the inner container in position.

- 2; A shipping container comprising an outer cylindrical container of comparatively thin wood veneer; a circular bottom ofsimilar material having slots arranged in the periphery thereof; a false circular bottom of similar material having a concentric circular aperture therein; means arranged to retain a space between the bottom and the false bottom; an inner cylindrical con tainercomposed of comparativelythin Wood veneer projecting through the aperture inthe false bottom and to the bottom of the outer container so as to provide an annular space above and belowthe false bottom; a suitable cover secured to the top of the outer container and arranged to retain the inner container in position; and a suitable Waterproof material surrounding the inner container. U i

3. A shipping container comprising an outer cylindrical container of comparatively thin wood veneer; a bottom of similarmaterial having slots arranged in the periphery comparatively thin wood veneer projecting signatures in the presence of two subscrib- 10 through the aperture in the false bottom ing witnesses. and to the bottom of the outer container s0 as to provide an annular space above and below the false bottom; and a suitable cover secured to the outer container and having a door therein by means of Which the inner container may be re-iced.

In Witness whereof We hereunto set our WALLACE P. ANGELO. A HEATH ANGELO. FRANCIS B. RUSSI.
